SHOES WITH TITANIUM SPRINGS

Definition:  Spira shoes have titanium springs in the sole of the shoe.  The springs are at the heel and metatarsal areas in some shoes and at the heel only in others. 

The springs allow less impact on the foot and joints (20% less) and give a push at toe off (87% more than the foot alone provides).  In fact, the shoes are banned from competitive track and field, considered too much of an assistive device.

Benefits:  These shoes reduce step shock and joint wear and tear tremendously, much as working out on elliptical devices provides the benefits of weight bearing exercise without the adverse and unnecessary negative effect wear and tear on feet and joints.
